With this i have no idea how to don"t ignore this one helllpconsider the following graph of a quadratic function. write the euqation for the quadratic function in standard form. the graphs y-intercept is 7 and vertex is (-3,-2)

Write the vertex form of the equation and find the necessary coefficient to make it work.
.. y = a*(x +3)^2 -2
.. = ax^2 +6ax +9a -2

You require the y-intercept to be 7. So, for x=0, you have
.. 9a -2 = 7
.. 9a = 9
.. a = 1

The equation you seek is
.. y = x^2 +6x +7

Idk idk idk idk idk idk idk idk

The answer is a hope i
